unauthorised money deduction

I would just like to say that what happened a few minutes ago was disgusted from absa as they were not authorized to take money from account as that was the only money available how will I live for the rest of the month, please assist and reverse the money deducted immediately as I will really take this matter further if not assisted urgently. Now I see why I was advised not to bank with absa and I think I will have to leave if such service received is not fair. Please please reverse the funds and lets make arrangements.
